Starting Issue. Need multiple opinion.

Okay so my explorer has a mind of its own and doesn't start all the time. It has a issue of cranking, put it has trouble turning over. I have replaced the fuel filter thinking that was causing the problem with a air lock from being dirty. Ive also gotten a tune up and they didn't solve the problem. I also tried replacing the fuel pump relay hoping that was going bad but they didn't solve anything either. Does anybody have any other ideas?

I though it would be the starter but some people were telling me that the car wouldn't be cranking as fast as mine is currently doing.

dont suppose you have a video of the problem. could give us guys a better understanding of exactly how it cranks over, just a thought. have you had the battery tested?
also what engine do you have 5.0, 4.0 ovc, or ohv?
